Who Discovered Nickel?

Who Discovered Nickel?
Known as a chemical element that is identified with the atomic number of 28 and symbol of Ni, nickel is a metal that is ductile and hard. This element is classified under the transition metals. The metal is usually present in alloys like taenite and kamacite. It is also present in iron meteorites. Because of the distinct characteristics or properties of this element, it is widely used in producing metal apparatuses. In order to know more about this element, it is best if we start with the history of the discovery of nickel. Historical Background Who discovered nickel? This transition element was discovered by Swedish chemist Axel Fredrik Cronstedt in 1751. The discovery of the element happened when the chemist isolated copper from niccolite. Instead of extracting the metal, he isolated another element with silvery white color that Cronstedt named nickel. Even if Cronstedt was recognized as the scientist who discovered the element, there were evidences, which proved that nickel was used...

Who Discovered Aluminum?

Who Discovered Aluminum?
Though today it is one of the most common metals in the world, there was a time when aluminum was actually one of the rarest and most precious. It took the scientists who discovered aluminum years of experimentation before they succeeded in refining this elusive element. Aluminum originates from the compound “alum,” given that name by French chemist and politician Louis-Bernard Guyton de Morveau in 1761. From as far back as 1787, scientists had hypothesized the existence of an unknown base metal in alum. While not quite the man who discovered aluminum, British chemist and inventor Sir Humphry Davy, can be credited for naming it (first as “alumium” before being given its current designation) in 1808. It was in 1825 when a Danish chemist and physicist named Hans Christian Oersted developed a way of extracting small amounts of aluminum from alum by having anhydrous aluminum chloride react with potassium amalgam to produce a chunk of metal with properties similar to those of tin.

Who Discovered Earth?

Who Discovered Earth?
Discussing who discovered earth may take the topic back to the Garden of Eden. This was where man was said to first discover his planet. However, discovering earth can mean a lot of things to a lot of people. Who Discovered Earth was Not the Center of the Universe? Discussing who discovered the planet may be in terms of who did so to prove that it was not the center of the universe. In ancient times, earth was thought to be located in the center of the universe. All other planets, including the sun and stars, revolved around it. It was among the central teachings of the church. To believe otherwise was considered heretic. Nicolaus Copernicus was the man who discovered earth as merely among planets that revolved around the sun. He presented a model of the solar system that was heliocentric in nature. This later became among the few established facts about earth’s discovery. Galileo later confirmed Copernicus’ statement. Who Discovered Earth was Not Flat? Ancient people also believed...

Who Discovered the Dead Sea Scrolls?

Who Discovered the Dead Sea Scrolls?
The Discovery of the Dead Sea scrolls The famous Dead Sea Scrolls were discovered in 1947 in Qumran by a group of Bedouin goat herders. Qumran is located just a kilometer from the Dead Sea. While looking for a stray goat there, the herders wandered into a cave. They found a set of jars containing old manuscripts. Recognizing some value in this strange find, the Bedouin sold them to a shoemaker named Kando. Kando specialized in the buying and selling of antiquities. Of the seven jars that he’d bought, he sold three of them to Eleazar Sukenik of the Hebrew University. He then sold the other four to Mar Athansius, a member of the Syrian Orthodox monastery. Athansius later brought his scrolls to American School of Oriental Research. Not long adter that, western scholars gathered around the Dead Sea Scrolls like fireflies around light.

Who Discovered Copper?

Who Discovered Copper?
Introduction Who discovered copper? Nobody knows. But evidence suggests that copper was the first metal ever discovered and used by man. Or at least one of the oldest. In modern day Iraq, archeologists once found a copper pendant over 10,000 years old. Unlike silver, copper is often found uncompounded in its natural state. So it is likely that humans learned to use copper first, perhaps along with gold and meteoritic iron. History of Copper Two of the world’s oldest civilizations made use of copper – Chaldea and Sumer. They used copper to make military equipment such as bows, arrows, spear heads and helmets. Archeologists have also unearthed small items like copper pins, harpoons blades and pots made of bronze (a copper alloy). Sumerian craftsmen made beautiful sculptures made from copper and mounted them on walls. The Imdugud Relief is a fine example of this. It dates from 3,100BC and shows an eagle with the head of a lion, holding a stag in each claw. Copper can be mixed with other...
